Note1: When you use the multimeter to measure the resistor of the transistor, because of
the capacitor in the circuit, it will cause the changing of the values when you measure the
DS and GD. So we recommend you measure the diode forward voltage of SD, and the
resistor of GS. These two values can reflect the situation of the transistor more correctly.
Note2: If one or more of them were damaged, please replace all of them.
3.1.1. Drivers (This part is only used for repair checking)
Note: Drivers usually need to be checked when users want to repair the boards. Because
when power devices were damaged, the high voltage will rush to driver circuit through the
gates of power devices.
The reference of the resistors list as below:
R52/R62/R81/R87/R92/R93/R115/R119 All of the resistors are (22R 1206)
